Title:
HIGH TOUGHNESS, HIGH CASTING PERFORMANCE, HEAT TREATMENT-FREE ALUMINUM ALLOY STRESSED MEMBER MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/036672
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of metal materials, and specifically relates to a high toughness, high casting performance, heat treatment-free aluminum alloy stressed member material, and a preparation method therefor. The high toughness, high casting performance, heat treatment-free aluminum alloy stressed member material comprises the following components in terms of mass percentage: Si: 8.5-12.0%, Mg: 0.10-0.35%, Mn: 0.25-0.4%, Cr: 0.02-0.14%, V: 0.02-0.38%, Sr: 0.01-0.04%, Ti: 0.05-0.11%, B≤0.005%, Ca≤0.05%, Zr≤0.1%, Zn≤0.1%, RE≤0.1%; the total amount of remaining impurities is less than or equal to 0.25%, and the remainder is Al. In the present invention, a die-casting part in a non-heat-treated state can have excellent comprehensive mechanical properties while ensuring that the alloy has good die-casting properties, thereby meeting the performance requirements of a die-cast stressed member.
